Principle Choices of Geographic Representation and
Cartographic Representations
This exercise has two parts that can be broken up into two separate exercises if time
doesn't allow for them to be done together.
In the first part of this exercise, take a close look at a map and describe how the map
shows principle choices of geographic representation and cartographic representa-
tion. Start out by defining the purpose, the scale, and the area of the map and then
consider the principle choices described on pages [xx-xx] in the topic. On a sheet
of paper, make six rows for the choices: things or events, patterns or processes, pro-
jected or unprojected, abstract or accurate, few or many associations, scale and
areas. In one column for each row, write a few words explaining the choices as you
look through the map. After you've filled in all the choices, create another column
and point out the relationships to other choices. In the second part of this exercise,
together with a neighbor in class, prepare a description of the choices you would
make to create a map for a purpose. It could be the way to a weekend sport's event,
the bus routes in your town, commuter maps, or the like. You should start out by
defining the purpose, the scale, and the area of the map, and then follow the
choices described on pages xx-xx in the topic. On a sheet of paper, make six rows
for the choices, making sure to leave a place for you to show how a sample map will
look: things or events, patterns or processes, projected or unprojected, abstract or
accurate, few or many associations, scale and areas. In one column for each row
write a few words explaining you choice and in another column point out any rela-
tionships to other choices.
2.
Detail the Fundamentals of Geography and
Cartography in a Real-World GIS Application
Analyze an existing GIS application (national or global) and identify choice of projec-
tions, how GI is abstacted/derived from the data, scale choices, choice of symbols,
and what GIS components are used: software, hardware, people, and organiza-
tions.

EXTENDED EXERCISE:
Projections
Objectives:
Identify types of projections
Describe the properties preseved and sacrificed by each
type of projection
Relate projection to different orientations of geographic
areas
Overview
Projections are crucial for geographic representation and cartographic representa-
tions. You should be able to identify different types of projections and relate them to
